Estimate the bandwidth needed to serve a number of viewers at a given bitrate per stream. Enter concurrent viewers and bitrate per stream to see bandwidth needed and in gigabits when you calculate.
Worked example
Example calculated from the starting values. Enter your own values and press Calculate to get your result.
With the default inputs (concurrent viewers = 200, bitrate per stream = 5 Mbps), the results are: bandwidth needed 1,000 Mbps; in gigabits 1.00 Gbps.
Quick reference: concurrent viewers vs result
Reference table based on the example values; it is not your calculation result.
| Concurrent viewers | Bandwidth needed | In gigabits |
|---|---|---|
| 100 | 500 Mbps | 0.50 Gbps |
| 200 | 1,000 Mbps | 1.00 Gbps |
| 400 | 2,000 Mbps | 2.00 Gbps |
| 1,000 | 5,000 Mbps | 5.00 Gbps |
| 2,000 | 10,000 Mbps | 10.00 Gbps |
| 4,000 | 20,000 Mbps | 20.00 Gbps |
Frequently asked questions
What formula does this calculator use?
Bandwidth needed = users × br; In gigabits = users × br ÷ 1000. Variables: users = concurrent viewers, br = bitrate per stream in Mbps.
What do I need to enter?
You need concurrent viewers, bitrate per stream (Mbps). Results update as you type.
What is an example result?
With the default inputs (concurrent viewers = 200, bitrate per stream = 5 Mbps), the results are: bandwidth needed 1,000 Mbps; in gigabits 1.00 Gbps.
